味苦，酸咸，性寒无毒，入心肝大肠三经。主五内邪热，肠风五痔，汤火疡疮，男子
囊坠肿痛，阴疮湿证，妇人阴中痛痒，崩中漏下，明目补脑，杀蛊去风，黑发延年。酒服能
催生堕胎。枝，专主洗湿热诸疮，治九种心疼。皮，主中风拘挛，齿痛疳 ，消痈解毒，止
痛长肉。胶，主肝脏风，筋脉抽掣，及急风口噤，四肢不收，或毒风周身如虫行，破伤危急
。花与实同功，又主心痛及疔肿热毒，赤白下痢，小儿惊痫，景天为使。
按∶槐实之苦，能泄心火，酸寒之性，能伐肝经。经曰∶酸苦涌泄为阴，其功主降，故
又入大肠，以理下焦诸证，且催产难，夫虫之生也因于湿，风之生也因于热，湿热既去，又
奚庸虞。花枝皮叶，主治大同小异，久为痔疮要药。
味苦辛，性微温无毒，入心肺肝脾胃膀胱六经。主心腹一切气疾，癖症块，九种心疼，
止泻痢，除霍乱，健脾胃，消食积，定呕逆，下痰壅，辟邪气瘟疫，杀疟蛊清物。宜生磨
用，火炒令人胀，形如枯骨，苦口沾牙者良。
按∶木香辛入肺，苦入心，温宜脾胃，肝者心之母也，膀胱者肺所连也，故均入焉。盖
心乃一身之主，气血之所听命者也，有主则能塞气，肺气调则金能制木，而肝火自伏矣。凡
人有怒，则肝气拂逆，而反忤其元气，心有从肝之情而不能制，则肝气于是乎盛，或为拂逆，
或为气冲，得木香则心气畅而正气亦畅，肝气何拂逆之有哉？实心之行夫肝也，非肝之自行
也。东垣以黄连制之，恶其气行过于通畅，不无走泄之患尔。
雷公云∶凡使其木香是芦蔓根条，五盘旋，采得二十九日方硬如朽骨，硬碎，其有芦头
丁，盖子色青者，是木香神也。
槐实：味苦，酸咸，性寒，无毒，入心、肝、大肠三经。主治五脏内的邪热，肠风及五种痔疮，汤火烫伤疮疡，男子阴囊坠胀肿痛，阴部疮疡湿证，妇人阴中痛痒，崩漏下血，明目补脑，杀虫祛风，黑发延年。酒送服能促进分娩、堕胎。槐枝，专门主治清洗湿热引起的各种疮疡，治疗九种心痛。槐皮，主治中风引起的拘挛抽搐，牙齿疼痛及疳蚀，消散痈肿解毒，止痛生肌。槐胶，主治肝脏风邪，筋脉抽搐掣动，以及口噤急症，四肢不能收持，或毒风侵袭全身如虫爬行，破伤风危急重症。槐花与槐实功效相同，又主治心痛及疔疮肿毒热毒，赤白痢疾，小儿惊痫，以景天为使药。
按语：槐实的苦味，能泄除心火；酸寒的性质，能克制肝经。医经说：酸味和苦味具有涌吐和泄下的作用，属于阴的性质，其功效主要在于下降，所以又能入大肠经，以调理下焦的各种病证，并且能催产难产。因为虫类的产生是由于湿气，风邪的产生是由于热邪，湿热既然去除，又有什么可担忧的呢？槐花、槐枝、槐皮、槐叶，主治大同小异，长期以来是治疗痔疮的要药。
木香：味苦辛，性微温，无毒，入心、肺、肝、脾、胃、膀胱六经。主治心腹一切气机疾病，癖积肿块，九种心痛，止泻痢，消除霍乱，健脾胃，消食积，定呕吐逆气，降痰壅滞，辟除邪气瘟疫，杀灭疟疾蛊毒清物。宜生磨使用，火炒会导致人腹胀，形状像枯骨一样，苦味沾牙的为良材。
按语：木香辛味入肺，苦味入心，温性适宜脾胃，肝是心的母脏，膀胱与肺相连，所以都入这些经络。大概心是一身的主宰，气血听从它的命令，有主宰就能闭塞气机（此处指调节气机），肺气调和则金能制木，而肝火自然潜伏。大凡人发怒，则肝气拂逆，反而忤犯元气，心有顺从肝的情志而不能制约，则肝气于是强盛，或者为拂逆，或者为气冲，得到木香则心气通畅而正气也通畅，肝气有什么拂逆的呢？实际上是木香在行用肝的功能，而不是肝自己在自行运作。李东垣用黄连来炮制它，是厌恶它的气行过于通畅，不免有走泄的祸患罢了。
Huai Shi (Sophorae Fructus): Bitter, sour and salty in flavor, cold in nature, non-toxic. Enters the Heart, Liver, and Large Intestine meridians. It primarily treats pathogenic heat within the five zang organs, intestinal wind (Chang Feng) and five types of hemorrhoids, burns and scalds, swelling and pain of the male scrotum, damp sores of the yin, painful and itchy sensations in the female vagina, metrorrhagia and uterine bleeding, brightens the eyes and nourishes the brain, kills parasites, dispels wind, blackens hair, and prolongs life. Taken with wine, it can induce labor and cause abortion. The branches are specifically used for washing various sores caused by damp-heat, and treating nine types of heartache. The bark treats spasms and convulsions due to wind-stroke, toothache and gingival caries, dissipates abscesses and detoxifies, stops pain and promotes flesh regeneration. The gum treats liver wind, muscle spasms and twitching, as well as acute lockjaw, limbs that cannot be controlled, or toxic wind affecting the whole body like insects crawling, and critical cases of broken-skin wind (tetanus). The flowers and fruits have similar functions, additionally treating heartache, carbuncles and sores with hot toxins, dysentery with red and white discharge, and pediatric convulsions. Scrophularia japonica (Jingtian) is used as an guiding herb.
Commentary: The bitterness of Huai Shi can drain Heart Fire; its sour and cold nature can suppress the Liver meridian. The classics state: "Sour and bitter actions of surging and draining belong to Yin." Its efficacy is primarily descending, thus it also enters the Large Intestine meridian to regulate disorders of the lower jiao, and can facilitate difficult labor. Since worms arise from dampness, and wind arises from heat, once damp-heat is eliminated, what need is there for worry? The flowers, branches, bark, and leaves have largely similar indications with minor differences, and have long been a key herb for treating hemorrhoids.
Mu Xiang (Aucklandiae Radix): Bitter and acrid in flavor, slightly warm in nature, non-toxic. Enters the Heart, Lung, Liver, Spleen, Stomach, and Bladder meridians. It treats all qi disorders of the chest and abdomen, phlegm-food stagnation masses, nine types of heartache, stops diarrhea and dysentery, eliminates cholera-like vomiting and diarrhea, strengthens the spleen and stomach, resolves food stagnation, stabilizes vomiting and reflux, descends phlegm obstruction, wards off evil qi and plagues, and kills malaria and gu-poison substances. It is best used raw and ground; fire-roasting causes abdominal distension, resulting in a shape resembling dry bones. The high-quality material has a bitter taste that adheres to the teeth.
Commentary: The acrid nature of Mu Xiang enters the Lung; the bitter nature enters the Heart; the warm nature suits the Spleen and Stomach. The Liver is the mother of the Heart; the Bladder is connected to the Lung; therefore, it enters these meridians. Generally, the Heart is the master of the entire body, commanding qi and blood. With a master, qi can be regulated. When Lung qi is harmonious, Metal controls Wood, and Liver Fire naturally subdues. When people become angry, Liver Qi rebels and counteracts the primordial qi. If the Heart follows the Liver's emotional tendency without being able to control it, Liver Qi becomes excessive, either rebelling or rushing upward. With Mu Xiang, Heart Qi flows smoothly, and righteous qi also flows smoothly; how can Liver Qi rebel? In reality, it is Mu Xiang acting upon the Liver, not the Liver acting on itself. Li Dongyuan processed it with Coptis chinensis (Huanglian) because he disliked its qi movement being too smooth, fearing the risk of leaking vital energy.
Lei Gong stated: Whenever using Mu Xiang, one selects the root stems of the vine, which coil five times. After twenty-nine days from harvesting, it becomes hard like rotten wood. When crushed, if there is a rhizome node with a green cap, this is the spirit of Mu Xiang.
